Solar power is an efficient way to reduce your electricity bill without putting a budget strain. In recent years, solar power systems have seen a surge in their demand. Residential and commercial enterprises are moving towards the adoption of renewable sources of energy.

Moreover, to encourage solar power installation, the government of India has a range of subsidy programs designed to motivate the household sector to adopt this source of energy. On average 1 kW solar panel produces 4-5 units per day, and for an average household a 3kW solar panel can be sufficient. In this blog, we will look into how to plan for a residential solar panel setup and a 3 kW solar panel price in India with a subsidy.

Understanding the working of a 3kW Solar Power System

A 3kW solar power system can produce up to 15-20 units per day, which is enough to meet the energy needs of a small 2 BHK for a family of 4. A 3kW solar panel system consists of around 8 and 10 panels. The photovoltaic cells in solar panels absorb sunlight and convert it into DC; the inverter then transforms this DC electricity into AC that is used to power your electric appliances. In the case of surplus energy, the excess is fed back into the grid.

3kW Solar Panels Specifications and Installation

A 3kW solar panel price in India depends on many factors like solar panel type, inverter quality, location, government incentives and subsidies, warranty and maintenance, grid connection, and your energy needs.

Installation of a 3kW solar panel system in India is a complex task, but the rewards are great! The payback period for the solar panel is generally around 3-5 years depending on the specifications involved. High-quality components may cost you more but at the same time meet high energy requirements. The place you live is also vital and affects the 3kW solar panel price in India. A lot of states offer subsidies and incentives for solar panel installation, apart from the national subsidy yojana, i.e. PM Surya Ghar Muft Bijli Yojanaa where you get up to INR 78000 as a subsidy, thus lowering your overall cost.

3kW Solar Panel Price in India with Subsidy
